High Tensile Chain

Try trucking supplies and find some herc-alloy or herculoid chain used for holding down loads very hi tensile strength "relatively" light and expensive - if you break it youll really be in trouble - good thing is not many people can break it LOL

What you need is lifting chain,and not the chain used to secure loads on the back of the tucks.All recovery operations MUST be treated as lifting operations for obvious reasons.That is why we use RATED flexible steel wire rope for winching.Same goes for chain.It must be stamped(every few links)with SWL and chain grade (Tuff-alloy grade T80).Here are safe working loads for some of the lifting chain diameters. 6mm(thick) =1.1t , 8mm=2.0t , 10mm=3.2t and so on. You will be fine with 8 or 10 mm depending on the vehicle you use. Hope this helps.

If the drag chain is not stamped with SWL it can not be used for lifting.Regardless how strong it apears to be.It shouldn't anyway.Lifting chain can be used as drag chain.Lifting chain is the only one that should be used in vehicle recovery.Generaly, drag chains are not suitable for lifting.

Might be worth checking with your state laws before you spend any money to see what's legal. And don't forget that illegal tyres mean no insurance if you have an accident (even if the tyres didn't cause it).

I know Queensland has fairly small limits on increasing height, but you can increase width by 50% (on beam axled vehicles) - doesn't make sense to me.
